Resins, Fillers and glues

Cotton fibers or wood flour are better for your size of boats, Scotty ...can't remember the WEST designations for these (and you have to ask them what is in many of their fillers anyway...) Brian (puffs up chest) Yeah, I got my fillers all set man, I've built over 50 of these size boats For the record, I use aerosil, maple flower, and pine flower in different mixes depending on what I am doing. Between the three I get what I need. For backings and wood and gap filling I use wood, mistakes are recut, not filled, I know this is not always practical in larger vessels.

I am using the colloidal silica I used yrs ago for blister repair and it seemed to work then but I may not be using the righ amount. Today, I plan to buy another gallon of the West epoxy, pumps and fibers. Milled fiber does not thicken epoxy very well. While it is great for strong bonding it will definitely not make epoxy stiff enough to keep it from sagging. For fairing and filling I mix in microballoons first then slowly add silica to get the right consistancy. I don't use milled fibers. I tried them once but the lamination it created left the epoxy stiff. For the type of construction I do, stiff is not necessarily good. Scotty |
